How to Calculate Restaurant Food Cost Percentage (With Examples)

Food costs are one of the most important expenses in a restaurant. If ingredient prices increase or menu prices are set incorrectly, your restaurant's profit can shrink even when sales are growing.

Understanding your food cost percentage helps you evaluate menu profitability, set better prices, and make more informed business decisions.

In this guide, you'll learn how to calculate restaurant food cost percentage, see practical examples, and discover how to use food cost calculations to improve your restaurant's financial performance.

What Is Restaurant Food Cost Percentage?

Restaurant food cost percentage measures how much you spend on food ingredients compared with the revenue generated from selling food.

For example, if your restaurant spends $300 on ingredients to generate $1,000 in food sales, your food cost percentage is 30%.

A lower food cost percentage can indicate better ingredient cost control, but the right target depends on your menu, ingredient quality, pricing strategy, and overall business model.

Food cost should be evaluated alongside labor, rent, utilities, waste, and other operating expenses.

How to Calculate Food Cost Percentage

Use this simple formula:

Food Cost Percentage = (Food Cost ÷ Food Sales) × 100

Where:

Food Cost is the cost of ingredients used to prepare the food sold during the period.
Food Sales is the revenue generated from those food sales, excluding taxes where appropriate.

Example 1: Calculating Food Cost Percentage

Suppose your restaurant records the following figures for one week:

Food cost: $1,200
Food sales: $4,000

The calculation is:

Food Cost Percentage = ($1,200 ÷ $4,000) × 100

Food Cost Percentage = 30%

This means that 30 cents of every dollar in food sales goes toward food costs, leaving 70 cents before labor and other expenses.

That remaining amount is not net profit. Your restaurant still needs to cover its other operating costs.

How to Calculate Food Cost Using Inventory

For a more accurate picture of ingredient consumption, restaurants often calculate food cost using inventory records.

The formula is:

Food Cost = Beginning Inventory + Purchases − Ending Inventory

For example:

Beginning inventory: $800
Food purchases: $1,500
Ending inventory: $500

Food Cost = $800 + $1,500 − $500

Food Cost = $1,800

If food sales during the same period were $6,000:

Food Cost Percentage = ($1,800 ÷ $6,000) × 100

Food Cost Percentage = 30%

This method helps account for ingredients already in stock, new purchases, and remaining inventory.

For better accuracy, use consistent inventory periods and account for transfers, spoilage, staff meals, and other adjustments where relevant.

How to Calculate Food Cost for an Individual Menu Item

Restaurant-wide food cost is useful, but you should also understand the ingredient cost of each menu item.

Consider a chicken sandwich with these ingredient costs:

Ingredient

Cost per serving

Chicken $1.20

Bread $0.40

Vegetables $0.25

Sauce $0.15

Other ingredients $0.20

Total ingredient cost $2.20

The total ingredient cost is $2.20.

If the sandwich sells for $8.00, its food cost percentage is:

($2.20 ÷ $8.00) × 100 = 27.5%

This calculation helps you compare menu items and identify products whose ingredient costs may be too high relative to their selling prices.

Remember to account for portion sizes, preparation yield, and ingredient price changes. Packaging and other direct costs may also need to be tracked separately.

How to Set a Menu Price Using Food Cost Percentage

You can use a target food cost percentage as one input when setting menu prices.

The formula is:

Suggested Menu Price = Ingredient Cost ÷ Target Food Cost Percentage

Always convert the target percentage into a decimal before dividing.

For example, if a dish costs $2.40 in ingredients and your target food cost percentage is 30%:

Suggested Menu Price = $2.40 ÷ 0.30

Suggested Menu Price = $8.00

This is a starting point, not a guarantee of profitability. Before finalizing the price, consider customer demand, competitor prices, labor, rent, delivery commissions, taxes, and other business expenses.

A dish with a low food cost percentage can still be unprofitable if its total operating costs are too high.

What Is a Good Food Cost Percentage for a Restaurant?

There is no single ideal food cost percentage for every restaurant.

The appropriate target depends on several factors:

Restaurant type: A fine-dining restaurant may have a different cost structure from a quick-service restaurant.
Menu composition: Meat, seafood, fresh produce, and processed ingredients have different cost profiles.
Portion control: Inconsistent portions can increase ingredient costs.
Waste management: Spoilage, overproduction, and preparation waste affect actual costs.
Pricing strategy: Customers' willingness to pay influences how much you can charge.

Instead of relying only on a general industry benchmark, calculate your own food cost regularly and compare actual results with your business targets.

5 Ways to Control Restaurant Food Costs

1. Standardize Recipes and Portions

Use consistent recipes and portion sizes so every dish has a predictable ingredient cost.

2. Review Supplier Prices

Compare supplier prices regularly and monitor ingredients that have significant price fluctuations.

3. Track Inventory

Record stock levels and review inventory movement to identify waste, spoilage, and unexpected usage.

4. Review Menu Profitability

Compare each item's ingredient cost, selling price, and sales volume. A popular dish is not necessarily the most profitable dish.

5. Update Menu Prices When Necessary

When ingredient costs rise, recalculate your menu costs and review whether prices need to change. Make pricing decisions based on both cost and customer expectations.
